Cramped trains and delays blighted the first 11 days after London Overground took over the Enfield Town train line.

Mayor of London Boris Johnson was in buoyant mood when he announced the new service at Enfield Town station on June 1

The service runs to Liverpool Street through Bush Hill Park, Edmonton Green and Silver Street stations, but is yet to live up to its billing as London Overground struggles to replace trains used by Abellio and Greater Anglia.

Roger Green, who commutes into London from Enfield Town, described the service over the first 11 days as a “farce”.

He said: “I was not expecting an entirely seamless transition but it has been a complete farce. Not only have trains been delayed or cancelled but the trains are half the size, meaning unbearable conditions during rush hour.”

Today, three trains have been cancelled or delayed due to “congestion caused by earlier delays” but trains being cut from eight carriages to four has left many commuters feeling let down.

Imran Rahan, 46, said: “You can barely move, there are fewer seats. London Overground may have patted themselves on the back at the takeover but there have been no smiles since then.”

People have also taken to social media site Twitter to vent their anger at the service.

Matt Labban tweeted: “Will your service from Enfield Town ever run on time? Couldn’t think it could get much worse from Greater Anglia.”

Of the 11 days London Overground has run the service, there have been delays on at least seven days, with some trains more than ten minutes late.

Mike Stubbs, TfL’s Director of London Overground, admitted there has been disruption and blamed “reliability issues” from the rail stock they inherited.

He said: “We apologise to customers for the disruption to services last week, which was primarily caused by reliability issues with the trains we inherited on the route.

“Some of these trains are over 30 years old and we have been experiencing some technical issues with them. We are working hard with our operator London Overground Rail Operations to resolve these and improve reliability and customer satisfaction as we have done with the rest of the London Overground network.”

Commuters can expect trains to remain in a similar condition until 2018 when new walk-through air-conditioned trains are unveiled.
